Featuring stunning WUXGA resolution and 4,500 lumens of brightness, the ViewSonic® LS831WU Laser Projector is the ideal solution for modern business and education environments. Designed with a laser phosphor light source lasting up to 20,000 hours, this projector delivers long-term, virtually maintenance-free usage for any boardroom or classroom. With its 0.25 ultra-short throw ratio, HV keystoning and 4 corner adjustments, the LS831WU makes installation a hassle-free experience. What’s more, the ultra-short throw ratio allows you to place the projector just inches away from a wall or screen to give you a huge image for less cost than a comparably sized display. Powered by SuperColor technology for true-to-life images, and SonicExpert® technology for incredibly clear sound, the LS831WU delivers an immersive audiovisual performance.
